Today the U.S. Supreme Court granted certiorari in Riley v. California and United States v. Wurie, two cases involving the warrantless search of an individual's cell phone incident to arrest. The Court will need to determine whether the Fourth Amendment limits a law enforcement officer from searching through the troves of data that are stored on an individual's cell phone when that individual is arrested. Courts have previously held that officers can search an individual's person and effects when they place them under arrest. But modern cell phones enable access to a wealth of personal data, which is unrelated to the Government’s reason for securing an arrestee. For more information, see EPIC: Riley v. California and EPIC: Amicus Curiae Briefs.
